Build me a working private game server for Genshin style gameplay using this codebase, and make it easy to run from a fresh clone. I want the server to compile cleanly, start up without extra guesswork, connect to MongoDB, and include the account setup flow so I can create a user and log in with the client. Please make sure the handbook generation still works, or give me a simple way to skip it if it breaks on my machine.

If anything in the setup is outdated, please fix the docs so a normal person can follow them step by step. I also want the client patch to be buildable from the patch folder, and the instructions should explain how to use it with the game folder. Keep the current features that are already there, like the updated mob and gadget spawns, and don’t break the config options that need to be turned off for the server to work. If you need current docs or dependencies, look them up online and then wire everything together so it just works.
